Prompted by student concerns that courses taken under a "bogus" professor might diversely affect their academic records, two Pennsylvania state colleges have formed faculty committees to address the problems raised by the fraud, officials of the colleges said yesterday.

The committees will look into the issue of credit and grades for courses taught by Paul A. Crafton, a professor who used false identities to obtain teaching positions at the colleges.

Ray Burg, director of public relations at Shippensburg State College, said his college's committee has come up with three options for students who stand to lose course credit because of Crafton's arrest, to crase the course from their records, to maintain their original grades and take a remedial course, or to reenroll in the course free of charge.

At College, where Cealon was a products of contains, officials have not yet decided whether to invalidator Craton's rooms. Keth Lovis, vice-president for student affaire, said yesterday.

But he added that there will be no charge for those who wish to retake the course, and that students who needed the course to meet graduation requirements will be excused.

Crefton, whose fraud was discovered in February, had established 32 identities in addition to the two he used at the Pennsylvania colleges, including one in which he worked on secret military equipment at a naval research lab.
